COURSE PROPOSAL

EU PRACTICAL INSIGHTS

INTRODUCTION

Kajima Corporation has a rich history of operations and experience as a civil engineering construction company. The “enterprising spirit” drives the company and its employees to take on new and big challenges. One of the challenges that Kajima Corporation has taken on, is the construction of the first big offshore wind farm the Japanese offshore waters. Kajima Corporation has expressed the wish to obtain knowledge in the field of offshore engineering to aid the company in its challenge of constructing this new type of project in traditional time lines. DOB-Academy is an industry knowledge institute that puts the sharing of knowledge as a vocal point of the organisation.

DOB-Academy’s courses combine theory and industry practise and will provide participants with comprehensive background knowledge for them to prosper in their jobs. The company’s in-house experts are complemented by a great network of industry experts. Next to theoretical lectures, DOB-Academy can provide hands-on cases and share EU best practises in the different stages of an offshore wind farm design and project execution. Together, the total package from (background-) knowledge and hands-on experience is a golden formula in training people and equipping them with the right knowledge and tools for the job.
